My PCB failed. I sent it to HDD-Parts in Canada, they swapped out the BIOS chip, returned the PCB, but the HDD does not spin up, it is detected by the PC in Computer Management/Disk Management but fails when I confirm MBR. I sent the board back to Canada asking for it to be checked, it came back - no comment from them. So I decided to buy 3 old WD800’s and try swapping over the PCBs. The old drives were SATA not IDE, but surprise-surprise, the disk spun up, then clicked a few times seeking, but was not seen by the PC. I guess it was trying to find the matching reg ID in the zero sector, well that’s what the Google Machine said. If I found a matching make/model/bios PCB from an old 2005 IDE drive, will it power up and spin my WD800? Bottom line, I am not spending $500+ dollars to retrieve the data. More curiosity as to whether there is a way to get it going again. Any tips would be appreciated. Thanks to anyone who can advise.
Hi there and welcome to the WD community.
I have never tried this, since this is not supported by WD. Lets see if another user that has experience on this matter can help you out on this matter.
I gather you mean you have never tried swapping over PCBs, and do you mean this practice is not supported by WD?
Is it possible that you are facing a Power Up In Standby (PUIS) issue?
